How do I show a marker in Maps launched by geo URI Intent?

I have a application where I want to show different locations (one at the time, picked by user input) by launching Google Maps with their specific geo coordinates.

I'm currently using this (with real lat. and long. values of course):

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("geo:<lat>,<long>?z=17"));
startActivity(intent);

It's quite exactly what I want, except that it doesn't show any indicator or marker for the specified point. It only centers at it's location.

Is there some way to get the marker or something else included without using a MapView?

Solution 1:

Try this:

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("geo:<lat>,<long>?q=<lat>,<long>(Label+Name)"));
startActivity(intent);

You can omit (Label+Name) if you don't want a label, and it will choose one randomly based on the nearest street or other thing it thinks relevant.

Solution 2:

There are many more options to launch a Google map using an intent...

   Double myLatitude = 44.433106;
   Double myLongitude = 26.103687;
   String labelLocation = "Jorgesys @ Bucharest";

1)

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("geo:<" + myLatitude  + ">,<" + myLongitude + ">?q=<" + myLatitude  + ">,<" + myLongitude + ">(" + labelLocation + ")"));
    startActivity(intent);

2)

String urlAddress = "http://maps.google.com/maps?q="+ myLatitude  +"," + myLongitude +"("+ labelLocation + ")&iwloc=A&hl=es";
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(urlAddress));
    startActivity(intent);

3)

   String urlAddress = "http://maps.googleapis.com/maps/api/streetview?size=500x500&location=" + myLatitude  + "," + myLongitude + "&fov=90&heading=235&pitch=10&sensor=false";
        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(urlAddress));
        startActivity(intent);

The accepted answer is correct, except when your label has an ampersand (&) in it.

Looking at A Uniform Resource Identifier for Geographic Locations ('geo' URI):

Section 5.1 states:

if the final URI is to include a 'query' component, add the component delimiter "?" to the end of the result, followed by the encoded query string.

Unfortunately for us, doing this will also escape the '=' which is not what we want.

We should do this:

String label = "Cinnamon & Toast";
String uriBegin = "geo:12,34";
String query = "12,34(" + label + ")";
String encodedQuery = Uri.encode(query);
String uriString = uriBegin + "?q=" + encodedQuery;
Uri uri = Uri.parse(uriString);
Intent intent = new Intent(android.content.Intent.ACTION_VIEW, uri);
startActivity(intent);
